How can I block all selenium bots? I want to block all selenium project.
Explanation:
I have very big website for streaming anime etc. Minimum Monthly 30 million hit guest and member.
Some websites grab from our site video links. Using with selenium bot
Before we did check and block, user agent, rate limit, session id check many bots blocked but now someone still grab, change proxy IP, session-id again send the request for grab. So he/she bypass our rate limit etc tracker.

You won't be able to block the Selenium bots totally as there are specific measures to bypass almost all the bot detecting mechanisms. A couple of examples:
The navigator.webdriver flag can be modified to prevent Selenium detection.
The user-agent of Google Chrome used by Selenium can be changed for each execution.
The useragent of google-chrome used by Selenium can be changed amid execution.
Using rotating proxies to avoid detection.
Detection of bots by cloudflare can also be bypassed.
Detection of google-chrome-headless by Cloudflare can also be bypassed.
Error 1015: You are being rate limited by Cloudflare can also be bypassed.
tl; dr
Can a website detect when you are using Selenium with chromedriver?

After several request my scraping code blocked by target site with re-captcha. I use https://github.com/gocolly/twocaptcha to bypass captcha with selenium chrome driver. It works while bypass with selenium chrome driver but when I run my scraping code again and it still blocked.
my question :
Why my code still blocked when re-captcha already bypassed with
selenium chrome driver?
How to bypass this re-captcha block?
CAPTCHA, short for Completely Automated Public Turing test to tell Computers and Humans Apart, is explicitly designed to prevent automation, so do not try! There are two primary strategies to get around CAPTCHA checks:
Disable CAPTCHAs in your test environment
Add a hook to allow tests to bypass the CAPTCHA
Do you know any webapps/online tests/online firewalls that are trying to detect if user is using selenium/puppeteer/phantomJS or any other headless browser?
I've created my puppeteer online crawler. I've changed many different stuff like window.navigator object (user-agent, ~.webdriver etc.).
Now I want to make sure that it is undetectable.
There is a headless browser detection test which tests for the following:
Does the User-Agent contain the string "HeadlessChrome"?
Is navigator.webdriver set?
Is window.chrome unset?
Does the browser skip asking for permissions (like notifications)?
Are browser plugins unavailable?
Is navigator.languages unset?
If your browser answers any of these questions with yes, then you fail the test. For more information on the test, check out this post, which is a reply to a post called "Detecting Chrome headless, new techniques".
The author of the latter post also published another test test (code), which claims to be able to detect bots and crawlers. It performs various tests on browser attributes and generates a fingerprint of your browser.
Other "soft" tests done by websites, might include the mouse movement, scrolling behavior, IP address, etc. I doubt you will find many tests regarding these information as this is basically a cat-and-mouse game.
I'd like to crawl a set of random websites received from a URL generator, using Selenium's ChromeDriver with Crawljax to do static code analysis on the captured DOM states.
Is this potentially unsafe for the machine doing the crawling?
My concern is that one of the randomly generated sites is malicious and that execution of JavaScript from ChromeDriver (which is used to capture the new DOM states) infects the machine running the test somehow. Should I be running this in some kind of sandboxed environment?
--edit--
If it matters, the crawler is implemented entirely in Java.
Simple answer, no. Only if your afraid of cookies, and even if you are, your machine isn't.
It's hard to say it's very secure,you should aware of that there is no absolute secure in network.Recently,a chrome RCE has been put out,details:
SSD Advisory – Chrome Turbofan Remote Code Execution – SecuriTeam Blogs
Maybe this can effect on Selenium's ChromeDriver
But you can do some enforce on your system,such as change your firewall mode to white list,only allow your python script and selenium to access internet on port 80,443.
Even if your system pwned by RCE,the malicious code still can't access internet,unless it inject to you python process(I think it's very hard to do with js script in Browser RCE).
Another option:Install HIPS,if your python script want to do anything else but crawl web page(such as start an other process) or read/write some other files,you will know it and decide what to do.
In my oppion,do your crawl thing in a VM and do some enforce on firewall(Windows firewall or Linux iptables),shutdown useless services in windows.That's enough.
In a word,it's diffcult to find the balance between security and convenience and do not believe your system is unbreakable
I'm testing a website which uses cookies for security. Every time a user logs in with a different device or browser they must go through an intensive (email and phone keys) identity verification process. My backup/restore process uses a Firefox addon and works for manual testing.
However when I run Selenium I get triggered to go through the ID process every time. So either Selenium is not using the cookies, or is being given a different browser ID for some reason.
I set a breakpoint to check my cookies are loaded in the Selenium Firefox browser window, but my addon is not available in Selenium Firefox instances.
Selenium documentation is very slim on cookie use:
http://www.seleniumhq.org/docs/03_webdriver.jsp
So any info much appreciated.
I would like to learn more about how selenium works. And to specifically answer the question: is it possible to know if someone is programatically accessing my website at a low rate using selenium webdriver?
edit: this is quite related, but it is dated Selenium Webdriver is detectable
Also, there is a recent specification for webdrivers that includes a webdriver-active flag http://www.w3.org/TR/webdriver/#dfn-webdriver-active-flag
No, you can't reliably determine if a human or a selenium process is interacting with your system. All your server sees are http requests.
